Answer 1

(8ч29мин-3ч44мин)*4=19 часов

Answer 2

To calculate the expression (8 hours 29 minutes - 3 hours 44 minutes) * 4, we need to convert the time into a single unit (minutes) and then perform the calculation.

Step 1: Convert the time to minutes 8 hours and 29 minutes = 8 * 60 + 29 = 509 minutes 3 hours and 44 minutes = 3 * 60 + 44 = 224 minutes

Step 2: Perform the subtraction (509 minutes - 224 minutes) * 4 = 285 minutes * 4 = 1140 minutes

Step 3: Convert back to hours and minutes 1140 minutes = 1140 / 60 = 19 hours (with a remainder of 0 minutes)

The final result is 19 hours.
